The 14C AMS system at The University of Georgia

Rafter radiocarbon sample preparation and data flow: Accommodating enhanced throughput and precision

“…A replacement Compact AMS system, incorporating an extended beamline enabling 10 Be and 26 Al measurement was ordered from NEC in November 2008. Apart from the extended beamline, the new XCAMS system is nearly identical to the NEC CAMS-500 systems for 14 C measurement [3][4][5] the MC-SNICS Cs-sputter source with spherical ionizer, and is based on the 1.5SDH-1 Pelletron system (Fig. 1).…”

Computer simulation of MC-SNICS for performance improvements

“…2.2. The C À current was set to 100 lA, which was reported by Roberts et al using similar settings [7], and three different emission angles with initial energies of 25 eV were applied in the simulation. It is seen that the beam almost completely fills the 6.5 mm diameter ionizer hole.…”

Compound specific radiocarbon content of lignin oxidation products from the Altamaha river and Coastal Georgia

“…These instruments include Thermo-Finnigan isotope ratio mass spectrometers and National Electrostatics Corporation's accelerator mass spectrometer. The University of Georgia's Center for Applied Isotope Studies accelerator mass spectrometer is referred to as the UGAMS system [10,11]. Less common is the approach to collection of specific biomarker compounds required for AMS 14 C determination.…”
